Homer Wright rosettes are a type of rosette in which differentiated tumor cells surround the neuropil.[1] Examples of tumors containing these are neuroblastoma, medulloblastoma, pinealoblastoma, and primitive neuroectodermal tumors of bone. Homer Wright rosettes are considered "pseudo" in the sense that they are not true rosettes. True rosettes are Flexner–Wintersteiner rosette, which contain an empty lumen. Homer Wright rosettes contain abundant fibrillary material. They are named for James Homer Wright.
